• Crowning Benefits

     · Roller deflection means there is bending due to its dimensions, material, and the load being applied to the roll in its particular appliion. Therefore, roll crowning is one common method of reducing nip variation caused by roller deflection. Another benefit of crowning a roll .

  • Cold Work Annealing Process

    Cold rolling is often used commercially in order to produce sheet metal, plates, and bars. When a metal is cold rolled, it is plastically deformed as it is forced between the two rolls. The metal is compressed by the rolls and the plastic deformation is in the direction of the rolling. Unlike a tensile test, no necking occurs in the metal specimen.
